• Resumen

  • The article discusses the environmental impact of increased production at Canada's oil sands in Alberta. The author argues that oil in Alberta's tar sands, called bitumen, is among the most greenhouse gas (GHG)-intensive forms of petroleum to produce. Topics include a comparison of the volume of GHG emitted from oil produced from the production of conventional oil from Saudi Arabia versus bitumen, how bitumen is processed, and the challenge of reducing the use of all fossil fuels.
